Method Details

generateSound

public QASound generateSound(long sourceSample,
 double sampleRate,
 double[] delays,
 double[] amplitudes)

Description copied from class: QASoundGenerator

Generate a sound

Overrides:

generateSound in class StandardSoundGenerator

Parameters:

sourceSample - the sample number at which the source was generated

sampleRate - sample rate of data to receive the sound

delays - delays in samples from generation of the sound to it's reception on each hydrophone

amplitudes - amplitudes on a linear scale (notDB) which incorporates the system full scale and the spreading loss but doesn't yet contain frequency dependent attenuation.

Returns:

a generated sound.

getFrequencyRange

public double[] getFrequencyRange()

Overrides:

getFrequencyRange in class StandardSoundGenerator

Returns:

The nominal frequency range of the sound in Hz.

getDurationRange

public double[] getDurationRange()

Overrides:

getDurationRange in class StandardSoundGenerator

Returns:

the nominal duration of the sound in seconds.
